FILLlNG-R-EPLENISHING LOOM.

SPECIFICATION forming part of Letters Patent No. 710,023, datedSeptember 30, 1902. Application filed April 24. 1902. Serial No.104,447- (No model.)

To ctZZ whom, it may conserve:

Be it known that I, EDWARD S. STIMPSON, a citizen of the United States,and a resident of Hopedale, county of Worcester, State of Massachusetts,have invented an Improvement in Automatic Filling-Replenishing Looms, of

which the following descri ption,in connection with the accompanyingdrawings, is a specification, like characters on the drawingsrepresenting like parts. 7

In that type of filling-replenishing mechanism for looms wherein thefilling-supplies are held in a movable feeder the latter is movedintermittently to bring the filling-supplies one by one into position tobe transferred, and various means have been devised to effect themovement of the feeder. At first the desired movement was effected bythe partial unwinding of a strong spring which was wound automaticallyafter each transfer, the filling-supply or filling-carrier being forcedby a transferrer from the feeder against the stress of the spring, andupon return movement of the transferrer to normal position thefilling-carrier next to be removed was brought up with considerable jaror shock against a fixed stop, as in United States Patent No. 529,940.The strain to which. the filling-carriers were subjected was injuriousin its effects, and means were devised for effecting the movement of thefeeder and its stoppagein such amanner that the strain upon thefilling-carriers would be obviated, the use of the powerfuloperating-spring being eliminated. Such means are shown in United StatesPatent No. 651,715, wherein initial movement of the feeder is effectedby a very light spring always in operative condition, the initial feedermovement being effected independently of the transferrer upontransferring movement thereof, thefinal and main movement of the feederbeing effected by or through the transferrer on its return to normalposition, the locking of the feeder also depending upon the transferrer.In a still later patent, No. 680,169, the feeder is rotated by a clutch,which is set by operativenlovement of the transferrer, but which doesnot operate until return movement of the translocked by means of a lightand normally inactive spring, which is set or rendered active byoperative movement of the transferrer, and completes the movement of thefeeder positively as the transferrer resumes its normal position,stopping such movement independently of the filling-carriers. A veryefficient feeder actuation is thus produced, with a soft or easy initialmovement and a quick and positive completion thereof, and

definite stoppage, so that at no time is a filling-carrier subjected toany strain save that due to its engagement by the transferrer.

I have herein illustrated my invention in connection with arotatably-movable fillingfeeder in which the filling-carriers are heldinacircularly-arranged series.

Figure 1 is a transverse section of a portion of a loom having oneembodiment of my invention applied thereto, the parts of thereplenishing mechanism being shownin normal position and with thesection taken through the axis and between the end plates or disksforming the filling-feeder; and Fig. 2 is a view similar to Fig. l, butshowing the parts at the instant a transfer has been effected and justas the transferrer is about to return to normal position, the initialmovement of the feeder having been effected.

The stand A mounted on and near one end of the breast-beam A and havinga fixed horizontal stud a; the filling feeder or holder rotatablymounted thereon and comprising two parallel disks, one of which, as a,is herein shown to support the filling-supplies or filling-carriers Z);the hub a, connecting the disks; the transferrerf, fulcrnmed on a fixedstudf; the means for operating the transferrer to engage and remove thefilling-carriers one by one from the feeder to the shuttle S, and thefixed stop h for the endmost filling-carrier b of the series in thefeeder may be and are all substantially as shown and described in UnitedStates Patent No. 680,169, referred to, the filling-carriers being heldin a circularly arranged series in the feeder. The toothed wheel or diska rotatable with the feeder and shown as mounted on the inner face ofthe feeder-disk a, is also substantially as in said patent; but, as willappear hereinafter, this wheel a is operative not only for effectingmovement of the feeder, but also for maintaining it locked independentlyof the filling-carriers.

The transferrer f is herein shown as provided with an upturnedprojection or dog f which enters a notch of the disk or wheel a when thetransferrer is in normal position, Fig. 1, and locks the holder frommovement, the rear edge of the dog at such time bearing against the faceof the adjacent tooth, as 10, the notches of the disk being positionedto correspond with the location of the filling-carriers, so that the endmost one, b thereof will just bear against the stop h when the feeder islocked. At its outer end the hub of the transferrer is enlarged beyondthe stud f, as at f and provided with a socket f enlarged orcounterbored at its upper end atf and a rather light coiled spring S isseated in the socket, its upper end extending into the counterboredportion.

A starting device or pawl 19, upturned and bent at its upper end toengage the toothed disk a is enlarged at its lower end, as at p,

and provided with an elongated upright slot 13 to receive a fulcrum-studa extended laterally from the stand A the heavy end of the pawl normallymaintaining it in the position shown in Fig. l. The pawl is providedwith an upwardly-curved and forwardly-extended tail 19 which projectsover the hub of the transferrer, and at its free end the tail has alateral enlargement or flange 19 normally just above the end of thespring S the end of the tail entering the counterboref A depending lug pis shown on the tail to normally rest on the transferrer-hub f andacting with the weighted end p of the pawl to normally retain it in theposition shown in Fig. 1, and at such time the spring S is entirelyuncompressed and quiescentor inactive.

When the transferrer is swung downward to engage and transfer theendmost fillingcarrier, as b from the holder to the shuttle, suchoperative movement Withdraws the dog f from the disk a so that as thefillingcarrier is conveyed to the shuttle the feeder is free to be movedthe instant such fillingcarricr passes below the stop h. While suchoperative movement of the transferrer is taking place, however, the riseof the enlargementf on the hub f causes the spring S to be compressedbetween the tail p of the pawl 1) and the bottom of the socket f suchcompression being sufficient to lift the pawl and its tail bodily, asshown in Fig. 2, and thereby eifect a rotative movement of the feederjust as soon as permitted by the passage therefrom of thefilling-carrier being transferred. Such bodily movement of the pawl andthe slight accompanying rocking thereof are permitted by the elongationof the slot 19 The movement thus imparted to'the feeder is effectedduring the operative or transferring movement of the transferrermanifestly, and the next filling-carrier of the series is therebybrought into the position shown in Fig. 2 against the dogf While thismovement of the feeder may be very slight, yet it is suflicient to movethe tooth 10 of the disk a far enough to bring its rear face into thepath of the end of the dog f when the transferrer returns to its normalposition, and as it does so the dog will act upon the tooth 10 andcontinue and complete the feeder movement until the front face of thenext tooth 11 brings up against the rear edge of the dog, and the feederwill then be locked, with the endmost filling-carrier in position to beengaged upon the next operation of the transferrer. The feeder cannotmove forward during return movement of the transferrer until the head ofthe latter clears the filling-carrier adjacent thereto, and locking ofthe feeder is efiected just as such filling-carrier reaches the stop h.As the transferrer is returning to normal position the tension of thespring S gradually decreases and reaches its minimum upon completion ofthe return movement, the starting-pawl returning to its normal positionas permitted by the spring. This spring is entirely inactive orquiescent under normal conditions manifestly and can only become activeby or through operative movement of the transferrer, and at such time itimparts a soft or yielding movement to the feeder through the pawl 19.The stop h acts as a guide for the filling-carrier being transferred,and it also serves as a stop to prevent movement of the feeder whenunlocked until the fillingcarrier is moved below the lower end of thestop, the spring S being compressed during the instant the stop holdsthe feeder from feeding movement. The operative engagement of the pawland dog with the toothed disk a is effected in alternation, the pawlbeing rendered active by and during operative movement of thetransferrer, while the dog is rendered inoperative or inactive, and whensaid dog is rendered active upon return movement of the transferrer thepawl is rendered inactive.

By the present invention the movement of the feeder is efiected in aneffective manner without shock or jar to the filling-carriers and by theuse of a single and comparatively light spring which is absolutelyinactive under normal conditions.

Ihave herein shown one practical embodiment of myinventionandhavenotattempted ICC to show or describe the various changes ormodifications which may be made therein by those skilled in the artwithout departing from the spirit and scope of my invention.
